Howto Disable CTRL-ALT-DEL from shutting down in Ubuntu

If you want to disable CTFL-ALT-DEL from shutting down their server use the following procedure.

For Dapper, and earlier Users

1)If you are using Dapper Drake, or before, you will have to edit /etc/inittab with the editor of your choice.

sudo gedit /etc/inittab

2)Now, look for the line that looks like this:

exec /sbin/shutdown -r now "Control-Alt-Delete pressed"

This is what we want to change. delete whole line. Now, its up to you what you want to do. If you want it to just print a message, and then do nothing, enter this

"CTRL+ALT+DEL is disabled!!"

or any other message of your choice.

If you want it to execute a script, change the line to

exec /path/to/your/script.sh

Thats it! Now, you can leave your server in peace, and not have to worry about anyone pressing CTRL+ALT+DELETE, and shutting it down!

For Edgy,Feisty,Gutsy,Hardy Users

In Edgy, you have to edit /etc/event.d/control-alt-delete. Then, just follow the steps in step 2 of Dapper and Earlier.
